Step-by-step explanation:
Hope this helps!!!
multiply 6 x 6 to get 36 and 7 x 11 to get 77.
6/7 x 6/11 = 36/77
Answer: 138x + 27
Step-by-step explanation:
First you distribute the 3, creating 102x +27.
Then you combine like terms, creating 138x + 27
You can't do anything else so that's your answer.
Answer:
(4, 18)
Step-by-step explanation:
We can just pluck the x values into the equation: y = 5x -1 to see if the y values fit.
1. y = 5(4) - 1
= 20 - 1
= 19 (Nope, 18 is not 19)
2. y = 5(3) - 1
= 15 - 1
= 14 (Yep, same as option)
3. y = 5(0) - 1
= 0-1
= -1 (Yep, same as option)
4. y = 5(2) - 1
= 10 - 1
= 9 (Yep, same as option)
(6+3i)(6-3i) =
(6 x 6) (6 x -3i) = 36 - 18i
(3i x 6) (3i x 3i) = 18i + 9i^2
36 - 18i + 18i + 9i^2
36 + 9i^2
